CHIPPER GUARD Harry Brewer, Sidney, Nebr.

Application June 21, 1943, Serial No. 491,725

7 Claims.

My invention relates to chipping hammers, and has among its objects and advantages the provision of an improved safety guard.

Removal of flux or chips in connection with arc welded jobs is dangerous to the eyes and face of the operator, as well as nearby workers. While goggles have been devised for eye protection purposes, such goggles afiord limited protection, since the greater part of the face and body are not at all protected. Goggles are also objectionable in that they become uncomfortable to the wearer after long periods of use.

Accordingly an object of my invention is to provide a guard which comprises an efficient unit which may be attached to the chipping hammer to afford good protection, both to the operator and nearby workmen, in which the guard is so devised as to be readily applicable to a double chisel or cone and chisel head hammer, and in which the guard is so devised as to facilitate replacement of parts thereof which may become damaged.

In the accompanying drawing:

Figure 1 is a view illustrating a conventional hammer to which the guard is attached.

Figure 2 is a similar view but with the hammer rotated 90 degrees about the axis of its handle, and

Figure 3 is a sectional view taken along the line 3-3 of Figure 1.

In the embodiment of the invention selected for illustration, I make use of a hammer H] of a conventional type, wherein the head [2 includes a chisel l4 and a cone H5. The head i2 is attached to a handle [8, the drawing illustrating the handle as comprising a metal rod provided with a suitable grip formation 20.

A guard 22 is mounted on the handle l8 and arranged transversely of the head l2. This guard is centered on the head l2 and comprises a screen 24 having its edge margins clamped between annular members 26 of a split ring 28. The members 28 are concaved in cross section and arranged with their concavities opening toward each other and facing the screen 24. Screws 30 fixedly secure the members 26 and the screen 24 into a unitary structure. The curved contour of the members 26 provides a light weight and strong construction so as to not objectionably weight the hammer.

Means for attaching the guard 22 to the handle i8 comprises clamp extensions 32 fixed to the respective members 26 and substantially embracing the handle I8. Flanges 34 project from the curved portions of the extensions 32 for coaction with screws 36 which firmly clamp the extensions to the handle when tightened.

The screen 24 is provided with an opening 38 to snugly receive the hammer head I2. Figure 3 illustrates the guard 22 as lying in a plane transversely of the head l2 and COIIlIIlOIl to the axis of the handle l8. Thus the guard 22 is equally effective in its protective function in all directions, and the diameter of the guard is such as to afford ample protection for the operator, as well as others in nearby positions. The screen 2:3 is of sufficiently open mesh to provide suitable visibility, but the screen provides ample protection from chips which might otherwise cause harm to the eyes or face.

The split ring or frame 28 is easily separated for the purpose of substitutin a new screen, and the frame is easily and quickly attached to the handle 18 by merely tightening the screws 36.

Without further elaboration, the foregoing will so fully explain my invention, that others may, by applying current knowledge, readily adapt the same for use under various conditions of service.

I claim:

I. The combination of a hammer having a head and a handle attached thereto, a guard extending about the head in a plane transversely thereof, and means connecting the guard to the handle.

2. The combination of a chipping hammer having a head and a handle attached thereto, a guard extending about said head, said guard being of open construction to afford visibility, and means attaching the guard to the handle.

3. The combination of a chipping hammer comprisin a head and a handle attached thereto, a guard arranged in a plane transversely of said head and in the plane of said handle, and means attaching the guard to the handle.

l. The combination of a chipping hammer comprising a head and a handle attached to the head intermediate its ends, a guard comprising a frame, mesh attached to said frame and extending about said head intermediate its ends and transversely thereof, said mesh being detachably secured to said frame, and clamp means on said frame for detachably connecting the latter to said handle.

5. The combination of a chipping hammer comprising a head and a handle attached to the head intermediate the ends of the head, a guard comprising a frame, mesh having an opening receiving said head and attached to said frame,

and means on said frame for detachably connecting the latter with said handle.

6. The combination of a chipping tool having a handle attached thereto, a. frame comprising two sections, mesh having an opening receiving said tool and lying between said sections, means for detachably clamping said sections on said mesh, clamp elements attached to the respective sections and embracing said handle, and means for detachably securing said clamp elements to 10 said handle.

7. The combination of a chipping hammer comprising a head having a handle attached thereto, a guard comprising ring sections, a

guard sheet of open construction having its edge margins lying between said ring sections, said ring sections being concaved in cross section and opening in the direction of each other, means detachably clamping the ring sections on said sheet, clamp extensions attached to the respective ring sections and embracing said handle, said clamp sections being provided with flanges, and means coacting with said flanges to clamp said clamp elements to the handle, said guard and said clamp sections lying in a plane transversely of said head and in the plane of the axis of said handle.
